I didn't verify but the driveshaft shop guy said 3.5". He asked how much power I was going to make because he thought the 1350 joints were overkill. I told him 475 to 500 crank hp and he said this should be good. My 56 GMC with a stock 5.3L is running a much smaller shaft, but I just had a 70 chevelle shaft (that I already had) cut down to fit.
